My Sony home theater video center speaker don't work.
Check the connections between the speaker input on the rear of the unit, and the cable to the speaker itself, ensuring there are no weak spots or cracks. Check to make sure the centre speaker is securely connected to the correct port/socket on the rear of the unit. Also check settings of the surround in the unit's setup option - and if the display shows speaker icons and the centre one is not illuminated, it is probably OFF, or the selected mode/function does not require that speaker. If this is the case, change the function using the unit's function (mode) button, either on the front, or via the remote. (some home theatre systems have multiple modes/functions, for example MOVIE, DYNAMIC, DTS, 2 CH stereo, etc.)
It is also a good idea to do a 5.1 surround test - some DVDs have this as a bonus setup feature, but you can do this with a normal audio source, such as from a DVD or a TV program. You should hear a sound from each of the speakers, and if the unit has a volume control or each speaker does, make sure these are set to a relatively equal audible level.
If after trying the above, you still get no sound from the centre speaker, it is possible either the speaker itself or the unit has a fault. If it is the former, consider replacing the speaker. If it is the latter, this could be expensive in terms of parts and labour - as service technicians charge an arm and a leg for repairs to the amplifier circuit in these units.
In any event, try the basic, simple steps above before considering any further action. It could just be a faulty speaker, a bad connection, an incorrect connection, or a mode/function setting is wrong, causing the speaker to be OFF.
